Casement Window Lock Replacement

A quick learner from Louisville says:
I need to replace this broken casement window lock. The intact lock picture is from the opposite side of the same tri-panel window and rotates in the opposite direction. I have matched the broken lock to the dimensions for your 38-095 (medium slider) and 38-096 (long slider). How do I know which of the two I need? The window is approx. 66" tall by 19" wide.

Hello, thank you for posting,

The difference between the 38-095 and 38-096 locks is the projection of the locking fork. Please review the dimensions below to see how they compare to your original to confirm the best fit. Let us know if you have any additional questions!
